Says Lloyd Marcus (black, unhyphenated-American) FWIW;

The Left published a cartoon depicting former black Secretary of State Condolezza Rice as an Aunt Jemima; another depicted Rice as a huge-lipped parrot for her Massa Bush. Neither were considered racist by their creators or publishers, or even widely condemned on the Left.

In opposition to black Republican Michael Steele’s campaign torun for U.S. Senate, a liberal blogger published a doctored photo of Steele in black face and big red lips made to look like a minstrel. The caption read, “Simple Sambo wants to move to the big house”. Not one Democrat denounced these racist portrayals of black conservatives.

Two wrongs don’t make a right, but maybe give some perspective. The dems did not alienate, and in fact did just fine with black Americans this last election.
